Question

What is Volkmann's Ischaemic Contracture ?

No spam pls. ​

Answer 1

Answer:

Volkmann’s ischemic contracture (ischemic compartment syndrome): The sudden complete occlusion (e.g., due to tight plaster cast) or laceration (due to supracondylar fracture of the humerus) of the brachial artery can cause paralysis of flexor muscles of the forearm due to

ischemia within a few hours. The muscles can tolerate ischemia up to 6 hours only. Thereafter they undergo necrosis and fibrous tissue replaces the necrotic tissue. As a result, muscles shorten permanently producing a flexor deformity characterized by flexion of the wrist, extension of the MP joints, and flexion of the IP joints, which leads to loss of hand power.

• Volkmann's contracture is a permanent flexion contracture of the hand at the wrist, resulting in a claw-like deformity of the hand and fingers.

• Passive extension of fingers is restricted and painful.
